Description

Technical Field

[0001] This utility model relates to the technical field of sealing plug disassembly and assembly devices, and in particular to a special tool for a dynamic sealing plug of an environmentally friendly gas cabinet. Background Technology

[0002] During the disassembly and assembly of the dynamic sealing plug in the environmentally friendly gas cabinet, the current lack of specialized and suitable tools forces workers to rely on existing general-purpose wrenches. However, this approach often comes with potential risks and challenges. Specifically, the design of general-purpose wrenches does not fully conform to the unique structure and size requirements of the dynamic sealing plug's disassembly and assembly groove. Therefore, during the application of force, the contact area between the wrench and the groove is limited, and the pressure distribution is uneven. This situation can easily lead to excessive force on the edge of the groove, resulting in damage such as groove wear, deformation, or even cracking. Once the groove is damaged, it directly affects the subsequent disassembly and assembly of the sealing plug. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a special tool for the dynamic sealing plug of an environmentally friendly gas cabinet, thereby facilitating the disassembly and assembly of the dynamic sealing plug.

[0004] This utility model provides a special tool for a dynamic sealing plug of an environmentally friendly gas cabinet, characterized in that: it includes a wrench rod and a wrench head, the wrench rod being connected to the wrench head; the wrench head includes a connecting post, a connecting plate, a connecting ring, and wrench teeth, the lower end of the connecting post being connected to the center of the connecting plate, the lower end of the connecting plate being connected to the connecting ring via multiple connecting rods, the inner wall of the connecting ring having a guide groove with an inner opening, the wrench teeth being installed in the guide groove, the wrench teeth being slidably connected to the guide groove; the number and position of the guide groove and the wrench teeth corresponding to the disassembly and assembly groove of the sealing plug, the outer wall of the connecting ring having a boss corresponding to the guide groove, the boss having a through hole communicating with the guide groove, an adjusting screw being installed in the guide groove, the adjusting screw being rotatably engaged with the through hole of the boss, the outer end of the wrench teeth having a threaded blind hole, the adjusting screw being threadedly engaged with the threaded blind hole of the wrench teeth.

[0005] Furthermore, the connecting post is provided with a through hole, through which the wrench rod passes, and the two are slidably engaged. Limiting blocks are installed at both ends of the wrench rod to prevent it from coming out of the through hole of the connecting post.

[0006] Furthermore, one end of the adjusting screw passes through a through hole on the boss and connects to the knob.

[0007] Furthermore, the lower end wall of the guide groove of the connecting ring is provided with an elongated guide through hole, and a limit pin is installed at the lower end of the wrench teeth, with the limit pin placed inside the elongated guide through hole.

[0008] Furthermore, the lower end wall of the wrench teeth is provided with a limiting screw hole, the upper part of the limiting pin is provided with an external thread, the limiting pin is threadedly engaged with the limiting screw hole of the wrench teeth, and the lower end of the limiting pin is provided with a hexagonal blind hole.

[0009] Compared with the prior art, the present invention has the following outstanding advantages:

[0010] 1. This utility model uses a knob to rotate an adjusting screw, which can cause the wrench teeth to extend or retract into the guide groove, thereby satisfying the sealing plugs of different sizes and specifications;

[0011] 2. The wrench teeth of this utility model are detachable. When the wrench teeth are damaged and need to be replaced, first use a hexagonal wrench to remove the limiting pin from the wrench teeth, and then rotate the adjusting screw to disengage the adjusting screw from the wrench teeth, thereby removing the wrench teeth.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 and 2 As shown, this utility model includes a wrench handle and a wrench head.

[0020] The wrench handle is connected to the wrench head.

[0021] The wrench head includes a connecting post, a connecting disc, a connecting ring, and wrench teeth. The lower end of the connecting post is fixedly connected to the center of the connecting disc. The lower end of the connecting disc is fixedly connected to the connecting ring through multiple connecting rods. The inner wall of the connecting ring is provided with a guide groove with an inner opening. The wrench teeth are installed in the guide groove and are slidably connected to the guide groove.

[0022] In the optimized solution, the connecting column is provided with a through hole, and the wrench rod passes through the through hole of the connecting column, with the two slidingly engaged. Limiting blocks are fixedly installed at both ends of the wrench rod to prevent the wrench rod from coming out of the through hole of the connecting column.

[0023] The number and position of the guide groove and the wrench teeth correspond to the disassembly and assembly groove of the sealing plug, and there can be one, two or more.

[0024] like Figure 3 and 4 As shown, the outer wall of the connecting ring is provided with a boss, which corresponds to the guide groove. The boss has a through hole that communicates with the guide groove. An adjusting screw is installed in the guide groove. One end of the adjusting screw passes through the through hole on the boss and is fixedly connected to a knob. The adjusting screw and the through hole on the boss are rotatably engaged. The outer end of the wrench teeth has a threaded blind hole, and the adjusting screw and the threaded blind hole of the wrench teeth are threadedly engaged. When the adjusting screw is rotated by the knob, the adjusting screw can drive the wrench teeth to extend or retract into the guide groove, thereby accommodating sealing plugs of different sizes and specifications.

[0025] The lower end wall of the guide groove of the connecting ring is provided with an elongated guide through hole, and a limit pin is installed at the lower end of the wrench teeth. The limit pin is placed in the elongated guide through hole to prevent the wrench teeth from coming out of the guide groove during the rotation of the adjusting screw.

[0026] In the optimized design, the lower end wall of the wrench teeth is provided with a limiting screw hole, and the upper part of the limiting pin is provided with an external thread. The limiting pin is threadedly engaged with the limiting screw hole of the wrench teeth, and the lower end of the limiting pin is provided with a hexagonal blind hole. When the wrench teeth are damaged and need to be replaced, first use a hexagonal wrench to remove the limiting pin from the wrench teeth, and then rotate the adjusting screw to disengage the adjusting screw from the wrench teeth.
